Dye transfer image process |
(57) A process for providing a color image comprising exposing a radiation sensitive layer
over a vapor deposited colorant layer and vaporizing the colorant to selectively transmit
the colorant through the exposed layer. The change in solubility, penetrability and/or
crosslinking or polymerization causes differential migration through the exposed layer.
